As powerful as diffusion is, cells sometimes must move materials in the opposite direction—against a concentration difference. This is accomplished by a process known as active transport. As its name implies, active transport requires energy.

Answer:
The correct answer would be D) tt.
Recessive traits need a homozygous condition to get expressed and to produce a particular phenotype. In contrast, dominant trait can be expressed in homozygous as well as heterozygous condition of the alleles of a gene.
Now, shortness is a recessive trait encoded by allele "t". Hence, allele "t" must be present in the homozygous condition in order to make the plant short.
Thus, the genotype of all the short plants in the field should be tt and the genotype of the tall plants would be TT or Tt.
The genotype<span> of an organism is defined as the sum of all its genes. The </span>phenotype<span>of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences

The conclusion that Torri produced is supported by evidence since she did not switch her dependent variable, giving the mouse a fair advantage of learning which knob to touch
